ELECTRICAL INFORMATION FOR ALL DOUBLE-INSULATED TOOLS Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protecting insulation. Double insulated tools do not need to be grounded. WARNING: The double insulated system is intended to protect the user from electric shock resulting from a break in the tool’s internal insulation.
